Buffet called bitcoin “rat poison squared” at the Berkshire Hathaway 2018 annual shareholder meeting held on Saturday, May 5.
During the said meeting, Berkshire vice chairman and long-time Buffett associate Charlie Munger commented that trading in cryptocurrencies is “just dementia”.

Buffett warned investors about investing in bitcoin and other cryptocurrencies in January.

“In terms of cryptocurrencies, generally, I can say with almost certainty that they will come to a bad ending,” he said. “If I could buy a five-year put on every one of the cryptocurrencies, I’d be glad to do it but I would never short a dime’s worth,” he added.
